摘要
Complete fuel conversion represents an important, but unresolved, aspect in Chemical Looping Combustion (CLC). Different system design approaches are currently being investigated to maximize carbon conversion in the fuel reactor. To achieve greater than ninety percent conversion of the fuel in "fluid-bed" type reducers will require that CLC systems be equipped with additional process equipment to ensure that unburnt fuel leaving the reducer is minimized. This paper presents results obtained from a laboratory test system simulating a char stripper design comprising two components; one for separating large char particles, based on material density differentials, and another for removing small char particles from the oxygen carrier (OC) leaving the reducer, based on elutriation. A test unit was designed, built and operated to identify optimum conditions for separating OC material from unburnt solid fuel - char. The results obtained are necessary for designing a high temperature unit operated at temperatures expected within a CLC system.
